Experimental Error
Much confusion surrounds this simple requirement you will have
to meet in most labs. Here you go! Understand and use it.
DEFINITION: An experimental error is a limitation of a procedure or an
instrument that causes an inaccuracy in the quantitative results of an
experiment. A human error is not considered a source of error under
this definition. Students should strive to identify, and understand,
experimental errors in their procedures whenever possible.

Chapter 1: (Introduction to Chemistry)
